SPECIFICATION forming part of Letters Patent No. 639,356, dated December 19, 1899. Application filed April 28, 1899. Serial No. 714.779. (No model.)

T 0 @ZZ wir/0m, t may concern,.-

Be it known that LTHoMAsWEBsTER CAMP- BELL,a citizen of the United States, residing at Energy, in the county of York and State of South Carolina, have invented a new and useful Subsoil-Plow, ofvwhich the following is a speciiication.

My invention relates to improvements in plows in which I employ a .subsoilingvlandside and share in connection with a revoluble furrow-turning moldboard adapted to be drawn through the ground without material increase in the draft on the team, because the subsoiler thoroughly breakslthe ground in advance of the moldboard, and thereby reduces friction to a minimum. Y

A further object of the invention is to provide a inoldboard which may easily be reversed at the end of the furrow without taking off said moldboard, thereby adaptin g the implement to service as a hillside-plow, because the moldboard may occupy a position on either side of the beam, and with said reversible moldboard is combined means by which it may be held at different angles to the line of draft.

A further object Vis to provide means by which the revoluble moldboard may be adjusted vertically to suit-the depth of the plow, said means serving to hold the moldboard in either of its several adjustments.

Vith these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a .perspective view of a subsoiling moldboard-plow constructed in accordance with my invention.-

' detail section through the bearing for the parts in each of the several .figures of the drawings.

The beam 10 of my improved plow is coustructed of a single flat piece of metal, preferably of steel, to secure maximum strength Without increase in the weight of the implement. To this beam is firmly secured the upright stock or foot 11, and through the upper end of said stock andthe beam are passed the fastening-bolts l2. The stock or foot is also constructed of metal and its front edge is beveled or inclined at 13 to produce a cuting edge on the front side of the stock.

The laudside 14 is cast in a single piece of metal,with a lateral foot-ange 15, and the upright part of the landside is inclined in a direction from the front end to the beveled edge 13 of the stock, said inclined edge of the landside being beveled transversely to produce the cuttingledge 16, which practically joins with the cuttingedge 13 of thestock, whereby the landside is made to serve the purpose of a colter in cutting through the soil, and the edges 13 16' of the stock and landside coact to sever the soil When the implement is drawn through hard ground. The sole-flange of the landside is extended beyond the colter edge 16, and in said landsde is produced a notch 17, which is adapted to receive a part of the point or share 1S. The. point is arranged to overlap the sole-flange at the frontend of the share or landside, and it is fastened firmly in place by a vertical bolt 19.

- To cut roots and obstructions in the path of the subsoiling-plow I, em ploy a rotary colter 20, which is suspended in a position over the colter of the landside by means of a hanger verse tie-bar 23. The handles are stayed in IOO proper position with relation to the beam by the braces 24. These braces are fashioned peculiarly to stay the handle-bars and to serveV as a guide for the carrying-bar of the revoluble moldboard. As shown more clearly by Fig. 3 of the drawings, the lower part of the braces 24 have straight parallel lengths 25, arranged to loosely embrace the rear end of the fiat beam and united firmly thereto by one or more transverse bolts 2G. The straight lengths 25 of the braces are attached together by a transverse bolt or pin 27, located at a suitable height above the beam, and above said bolt or pin 27 the braces diverge laterally, as at 28, in a manner to have the ends thereof bear against the inner faces of the handle-bars, said diverging ends of the braces being fastened to the handle-bars byA the bolts 29.

30 designates the carrying-bar for the revoluble mold board. This carrying-bar is made curved or angular, as at 3l, and its vertical member is prolonged or extended in adownward direction andis fashioned to produce an elongated spindle 32,which is of circular crosssection. At a point between the Hat carrying-bar and the cylindrical spindle a lockingdisk 33 is vfastened rmly to the carrying-bar orl made integral therewith for a purpose which will presently appear. A pair of bars 34 are made fast to the carrying-bars 30 by welding saidA bars 34 to the front end of the carrying-bar, and said bars 34 are extended forwardly above the plow-beam and the front ends thereof are bent or curved in a downward direction. said bars 34 lap the plow-beam 10, and a horizontal bolt 35 passes through the front ends of the bars and the beam in order to pivotally attach the carrying-bar to said beam. This carrying-bar is fitted slidably in the slot or .space which is formed by and between the parallel lengths 25 of the braces which afford lateral supports for the carrying-bar, and as said bar 30 is connected by a horizontal pivotbvolt to the beam it may be raised or lowered in a vertical direction to regulate the position of the revoluble moldboard relatively to the subsoiling-plowshare. As one means for supporting the carrying-bar in either of its several positions I employ an adjusting-bar 36,

which is pivotally attached by a bolt 37 to the carrying-bar, and this adjusting-bar is provided at its upper end with an offset-handle 38 and with a series of notches 3). Itis evident that the handle may be manipulated tov -raise or lower the bar 30, and the handle may y then be moved on its pivot 37 to make the pin i or bolt 2.8 enter eitherof the notches 39 in said lstandard 40, which is fitted snugly to the vertical spindle 32 of the carrying-bar 30.

This

A tubular standard is preferably cast in a single The curved front ends of' piece of metal, with an integral disk-shaped head 4l at its upper end, and this head is adapted to abut or bear against the lockingdisk 33 on the carrying-bar. The head of the tubular standard is provided on one side thereof with vertical apertures 42 43, and on the other side of the vertical axis ofsaid standard t-he head is, furthermore, provided with other apertures 44 45, the apertures 44 and 45 being located at diainetrieally opposite points for a purpose which will presently appear. The standard is, furthermore, provided with a radial pin or stud 46, which enters an annular groove 47, provided in the spindle 32 of the carrying-bar, and this construction permits the standard 40 to turn freely on the spindle without moving endwise on said spindle, thus connecting the standard and spindle together in a manner to preventvvertical displacement of the standard.

The tubular standard has its lower end enlarged to form a foot 4S, and in one side of this foot is produced a cylindrical cavity 49, which constitutes a bearing for the rotary disk, and arranged centrally in this cylindrical cavity or bearing 49 is a journal-pin 50, which is made fast with the closed side or end of the foot 4S. The rotary disk 51, which constitutes the moldboard, is a single piece of metal of concave or dished contour, and on the convex face of this disk is provided acylindrical hollow journal or stud 52. (See Figs. 4 and 7.) This stud constitutes the hub of the revoluble disk, and the stud is fitted in the `cavity or bearing 49, while the journalpin 50 enters the opening of the hollow stud 52, whereby the rotary disk is connected to the tubular standard by a joint which pernrits the disk to rotate freely on the standard,

which excludes dirt from the bearing, and which minimizes the friction between the coacting elements of the disk and the standard.

The disk 33 of the carrying-bar is provided with a horizontal plate 53, which extends rearwardly from the disk 33 and is provided with lugs 54. (See Figs. 2, 4, and 5.) One end of a lever 55 is fitted between said lugs and is connected thereto by a pivot-bolt 56.

, To this lever is connected a locking-pin 57,

the upper end of which is forked at 58 to embrace said lever, and the forked end of the pin is pivoted by a pin or bolt 59 to the lever 55. This lever may be raised to withdraw the locking-pin fromengagement with the perforated head of the tubular standard, thus permitting the standard to be turned lon the spindle in order to change the position ofthe rotary disk from one side to the other Aof the spindle. The locking-pin 57 is adapted to pass through an aperture 57L in lthe disk 33 of the carrying-bar, and this pin may be fitted in either of the openings 42 to 45, inclusive, in the head 4l of the tubular standard.v It will be observed that the tubular standard is adapted on withdrawal of the locking-pin to turn on the spindle of thecarrying-bar, 'and thus the standard may be adj ustedto change the position of the'rotary disk with relation the right or left hand side of the share in order to make its concaved side face in either direction, and the tubular standard, which carries said disk, may be fastened in place by the locking-pin for the rotary disk to occupy different angles to the line of draft. When the disk occupies a position on the right-hand side of the plow, the lever may'be adjusted to move the locking-pin into the aperture 42 of the standard-head 41, thus giving a certain angular position of the rotary disk to the line of draft; but if it is desired to increase this angle of the disk on the righthand side of the plow the standard may be adjusted to bring the aperture 48 into a position to receive thelocking-pin. Bywithdrawing thelockingpin from the head of the standard the rotary disk may be shifted by turning the standard on the spindle to the left-hand side of the plow, and the angle of the rotary disk to the line of draft may be changed by making the locking-pin t in either of the apertures 44 or 45 on the head of the tubular standard.

From the foregoing description it will be observed that the standard and the rotary disk which is mounted thereon may be raised or lowered by adjusting the notched bar 36 into engagement with the pin or bolt 27 by the braces 24. This provides for the vertical adjustment of the rotary disk with relation to the share; but such Vertical adjustment does not interfere with the rotary adjustment of the tubular standard on the spindle in order to shift the rotary disk with relation to the share; nor does either of the adjustments heretofore described interfere with the revoluble motion of the disk on the tubular standard.

To provide for proper cleaning of the rotary disk, I employ a cleaner-shovel 60, which is provided with a shank 6l, having an eye 62. An arm G3 ismade fast to or integral with the head 4l of the tubular standard, and this arm is adapted to tit in the eye of the shovel-shank, whereby a binding-screw 64, which is mounted in the shank, may engage with the arm to hold the shovel in proper relation to the face of the rotary concave disk 5l.

When the subsoiling-plow is used in wet land, I prefer to employ a conical drag 65, which is provided with a chain or other flexible connection 66, that is attached to the heel of the share. This conical drag is adapted to trail in rear of the subsoiiing-share, and it serves the purpose of opening a drain in the wet ground. A clevis 68 isl connected adjustably to the front end of the plow-beam. Said beam has an inclined series of vtransverse apertures 69, and in its end edge is a series of notches 70. The clevis G8 isprovided with two bolts 7l 72, the bolt 7l fitting in'either of the apertures 69, while the bolt- 72 lits in either of the notches 70 in the beam, whereby the clevis may be adjusted to inclined or horizontal positions on the front end of the plow-beam to change the line of draft thereon. f j

The subsoiling-plow of my invention may be used for various purposes, and it is especially adapted for gardening purposes by truckfarmers for the cultivation of beets and cotton and for preparing the ground for planting` crops. The revoluble disk or moldboard is adapted to be reversed at the end of a furrow without detacliing said disk from the plow, and thereby adapt the implement to hillside-work. luble disk at an angle to the line of draft does not materially increase the draft of the plow, because the colter and subsoiler breaks the land thoroughly and minimizes the friction, and the implement is thus adapted to perform a maximum' amount of service with little attention and without material increase in the draft. The several parts of the structure are simple and durable in construction, and

The employment of the revothey are arranged for easy access to permit of the adjustment of the parts by the operator stationed at the rear end of the plow.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to Without departing from the spirit or sacricing any of the advantages of this invention. I also find it desirable to provide a stay to hold the stock or foot and the beam in firm relation one to the other, and thereby brace the beam. This brace is indicated at 73 on the side of the plow-beam` opposite to that side to which the stock l1 is fastened, and said brace has an angular arm '74, (see Fig. 2,) arranged to have its lower end bear against and be secured to the foot or stock, as at 74,

IOO

The horizontal part of the brace is offset near IIO jor length of the beam to enable the arms 34, l

the clamp 2l, and the handles to be fitted or attached to the beam Without hindrance from said brace.
